McIntosh MC501 Amplifier (Pair) The MC501 Monoblock Power Amplifier has been designed to meet the expectations of the most demanding audiophile. Delegating an individual amplifier to each speaker eliminates any chance of interaction between channels and expanding into multi-channel formats is as easy as adding additional amplifiers. Quad-Differential Circuitry, exclusive to McIntosh, reduces noise and distortion to their lowest possible level. While the MC501 delivers a massive 500 watts of continuous power into 2, 4, or 8-Ohms and over 1200 watts or peak power into low impedances, its noise levels are 124dB below rated output. That means that the MC501 combines super-high power with record-low levels of noise...nearly an impossible combination! The MC501 has a bold look yet is unmistakably a McIntosh. It features a 2-dimensional glass front panel containing a large peak-responding true-wattmeter, all illuminated with cool running, ultra long-life LED fiber-optic lighting. The chassis gleams in polished stainless steel and vertically mounted connectors at the back make attaching cables easier and takes up less shelf space. Both unbalanced and balanced inputs are provided along with three sets of huge, gold-plated speaker binding posts for high-performance speaker cables.
